Call listings and discuss their rentals by pretending to be a tenant.Rent is the one thing you have VERY LITTLE control over. 

I'd like to infiltrate one of these posers, pretending to be an unsuspecting tenant and showing up with a cop.

I'll pretend I am Mike Rossi for a moment:Rent: $850Expenses: $425Mortgage Payment: $673Monthly Loss: $248 OUCH!!

If they don't spend the COGS, there is no revenue.Next, look at the following expenses and zero them out (pretend they are not expenses)TelephoneInternetVehicle ExpensesThis is because these are common expenses that everybody has.  

It builds on itself.So lets take your current rental in Belcamp and pretend that you don't own it yet.

Pretend that you are the end buyer when making offers.

The same unit in certain other areas of town would rent for probably $600.If you're trying to figure out how much you can get for a particular rental, just pretend you're looking for a unit like that for rent and search online. 

I hope this helps, and no I do not pretend to know everything.

I don't show up anywhere on title and that's the way I like it.I highly recommend you not waste your time with properties worth less than $100K and spending countless hours trolling Craigslist building a pretender buyers list.

Also the policy of extend and pretend helped.
